| // CLASS: uvm_test |
| // |
| // This class is the virtual base class for the user-defined tests. |
| // |
| // The uvm_test virtual class should be used as the base class for user-defined |
| // tests. Doing so provides the ability to select which test to execute using |
| // the UVM_TESTNAME command line or argument to the <uvm_root::run_test> task. |
| // |
| // For example |
| // |
| //| prompt> SIM_COMMAND +UVM_TESTNAME=test_bus_retry |
| // |
| // The global run_test() task should be specified inside an initial block |
| // such as |
| // |
| //| initial run_test(); |
| // |
| // Multiple tests, identified by their type name, are compiled in and then |
| // selected for execution from the command line without need for recompilation. |
| // Random seed selection is also available on the command line. |
| // |
| // If +UVM_TESTNAME=test_name is specified, then an object of type 'test_name' |
| // is created by factory and phasing begins. Here, it is presumed that the |
| // test will instantiate the test environment, or the test environment will |
| // have already been instantiated before the call to run_test(). |
| // |
| // If the specified test_name cannot be created by the <uvm_factory>, then a |
| // fatal error occurs. If run_test() is called without UVM_TESTNAME being |
| // specified, then all components constructed before the call to run_test will |
| // be cycled through their simulation phases. |
| // |
| // Deriving from uvm_test will allow you to distinguish tests from other |
| // component types that inherit from uvm_component directly. Such tests will |
| // automatically inherit features that may be added to uvm_test in the future. |
